Expression of miR-409-5p in gestational diabetes mellitus and its relationship with insulin resistance

Expression of miR-409-5p in gestational diabetes mellitus (GDM) and its relationship with insulin resistance were explore. One hundred and forty-nine pregnant women who underwent antenatal examination in Taizhou First People's Hospital were divided into a GDM group and a control group according to whether they had GDM or not. Serum miR-409-5p expression of the two groups was detected, and the levels of glycosylated hemoglobin (HbAlc) and other GDM-related biochemical indicators were measured. Fasting plasma glucose (FPG) was determined by glucose oxidase method, fasting insulin (FINS) was detected by radioimmunoassay, and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. The relationship between miR-409-5p and other biochemical indicators and insulin resistance was analyzed, and logistic multivariate regression was employed to analyze the risk factors of GDM. miR-409-5p was highly expressed in the serum of GDM patients. HbAlc, FPG, FINS, and HOMA-IR in pregnant women in the GDM group were markedly higher than those in the control group. The serum miR-409-5p in GDM pregnant women showed a positive correlation with HbAlc, FPG, FINS, and HOMA-IR (P<0.05). The insulin resistance group presented remarkably higher serum miR-409-5p level than the non-insulin resistance group. Moreover, it was found that elevated miR-409-5p, FINS, and HOMA-IR were all independent risk factors for the onset of GDM. miR-409-5p is highly expressed in the serum of patients with GDM, and it is positively correlated with insulin resistance index of GDM patients, which may be a potential target for clinical diagnosis and treatment of GDM.

Changes in intestinal flora, TNF-α, L-17, and IL-6 levels in patients with gestational diabetes mellitus

To study the changes in intestinal flora and different inflammatory factors in patients with gestational diabetes mellitus (GDM), a total of 80 patients with GDM treated in our hospital were selected as the study group. Meanwhile, another 60 normal pregnant women were selected as the control group. The contents of intestinal Bifidobacterium, Lactobacillus, and Bacteroides were measured in both groups followed by comparison of the incidence of intestinal flora imbalance. In the meantime, the levels of tumor necrosis factor alpha (TNF-α), interleukin-17 (IL-17), and interleukin-6 (IL-6) in serum were detected and compared between those two groups. Afterwards, multivariate logistic regression was used to analyze the risk factors related to GDM. The number of Bifidobacterium, Lactobacillus, and Bacteroides in the study group was significantly less than those in the control group. The incidence of intestinal flora imbalance in the study group was 33.75%, which is higher than that in the control group. The serum levels of inflammatory factors, including TNF-α, IL-17, and IL-6 in the study group were significantly higher than those in the control group. The result of multivariate logistic regression analysis showed that Bifidobacterium, Lactobacilli, Bacteroides, TNF-α, IL-17, and IL-6 were risk factors related to GDM. Patients with GDM are prone to intestinal flora imbalance with elevated different inflammatory, which affects immune function in patients and may play an important role in the development of diabetes mellitus.
